CLOSURE FOR CONTAINERS Filed Jan. 14, 1935 2 Sheets-Sheet 2 Patented Dec. 14, 1937 UNITED STATES PATENT OFFICE 2 Claims. (0]. 221-60) This invention relates to a closure for a container, such as a paste tube, liquid containing bottle, or the like.

It is the object of this invention to provide a closure which is non-removable from the container, is liquid and air tight when in closed position, permits of a completely freed opening when moved out of closing position, and principally facilitates opening and closing thereof. It is applicable to tooth pasteand shaving cream tubes or collapsible tubes of such character, but may also be used to advantage in bottles containing evaporative liquids or carbonated beverages, by reason of the positive sealing action ofthe closing member.

One feature of the invention resides in em- Dloyment of a closing valve contained within a non-removable but rotatable releasing cap, which valve is automatically opened upon' rotation of said cap, and without its removal.

Another feature of the invention resides in the automatic positioning of the cap with respect to the discharge spout of the container upon being rotated to open position, whereby the spout ex-= tends through an aperture in the top of the cap and is, wedged into sealing relation therewith to prevent the substance contained from entering the interior thereof.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Fig. 1 is a plan view of a col lapsible tube container embodying the invention. Fig. 2 is an enlarged side elevation of the neck and spout oi the tube with the cap and valve removed, part thereof being shown in section. Fig. Sis a plan view of the spout and. neck. Fig. 4 is a plan view of the valve. Fig. 5 is a side elevation of said valve with a. portion broken away. Fig. 6 is a plan view of the cap with the top removed. Fig. 7 is a section taken on the line l---! of Fig. 6. Fig. 8 is a sectional view illustratin the cap and valve in open position. Fig. 9 is the same as Fig. 8, illustrating them in closed position.

In the drawings there is illustrated a container I 0 which may be in the form of a. collapsible tube, as illustrated, a bottle or the like, having a neck H formed thereon terminating in a spout I2 through which a discharge conduit 13 extends. The neck is provided with cam grooves i4 about the lower portion thereof above which there extends a cylindrical portion l5 terminating in a ledge or shoulder forming a cam I6 which surrounds the conical spout l2.

Mounted about the neck ll there is a cap i'l having a cover or closure 18 provided with an aperture I9. Said cap is provided near its lower end with an inward projection 20 adapted to extend into the cam groove 14. Also provided in said cap there are oppositely-disposed recesses 2|.

Pivotally supported in the cap ll there is a valve comprising a frame 22 having oppositelydisposed projections 23 adapted to extend in the recesses 2| of the cap, whereby said frame will be pivotally mounted therein. Said frame car ries a valve head 24 in which a suitable gasket 25 is mounted, said head being supported bya neck 26 extending inwardly from the frame 22. Said frame is also provided with inwardly-extending ears 2'! and 28 on opposite sides thereof which are adapted to ride upon the shoulderlike cam l6. s

The valve frame, illustrated in Figs. 4 and 5, is pivotally mounted in the cap illustrated in Figs. 6 and '7, and the cap is then mounted about the neck H by passing the projections 2i! through the lead in grooves 29 of the cam. grooves 14. When the cap is rotated about the neck in one direction, the projections 20 pass to the lowermost portions of the cam grooves l4 carrying with it the valve frame which is thereby moved to closing position, as illustrated in Fig. 9, by the action of the cam IS on the ears 21 and 28. By this action, not only is the valve moved to closed position, but the turning of the cap draws it downwardly, so that the cover !8 engages and presses firmly upon the valve 26, forcing it against the end of the spout l2 and compressing the gasket 25 to seal the spout under pressure. When the cap is rotated in the reverse direction, the cam grooves i4, acting upon the projections 20, raise the cap to free the valve head 24 and give it clearance, the same rotating action causing the ears 2'! and 28 to substantially reverse their positions upon the cam it and swing the cap free of the spout and to one side thereof about the pivotal mountings 23. After the valve head has cleared the spout and moved to one side thereof, continued rotation of the cap lowers it until the spout l2 extends through the aper ture l9 and the cover i8 wedges about the periphery of the spout so as to effect a seal therebetween. as illustrated in Fig. 8.

From the foregoing it will be observed that a revolution of the cap in one direction will swing the valve to open position and move the spout through the aperture in the cap, bringing the cap into sealing relation about the periphery of the spout. A revolution in the other direction will raise the cap, close the valve, and lower the cap to clamping position thereon for sealing the opening of the spout.

The invention claimed is:

1. A closure for containers having a discharge spout provided with an orifice, said spout including a neck having a cam surrounding the same, a second cam surrounding said spout, a rotatable cap mounted over said neck and embracing said spout movable longitudinally of said neck by said first-mentioned cam upon rotation, a valve pivotally mounted in said cap having a head movable over said orifice for closing the same, and means associated with said valve and operable by said second-mentioned cam for moving said valve to closing position when said cap is rotated in one direction and into open position when said cap is rotated in the opposite direction.

2. A closure for containers having a discharge spout provided with an orifice, said spout including a neck-having a cam surrounding the same,

tudinal movement of said cap relative to said I l6 spout causing the latter to be projected through said aperture and wedged into sealing relation therewith upon said valve being opened, and upon reverse movement causing said spout to be closed by said valve and forcing it into sealing relation with the orifice.
